>	class DocComponentClass : public ListItem

	Author:		Tim_Browse (Xara Group Ltd) <camelotdev@xara.com>
	Created:	01/08/94
	Purpose:	This provides a class of objects which implement an interface to a particular 
				kind of	document component - for example a colour table, or a list of
				arrowheads.
				Each kind of object should register with the application on startup, and
				then when a document is created, each of these objects is asked to add
				an instance of a DocumentComponent object to it.  The DocumentComponent
				objects are the actual implemtations of the components.  For example, they
				contain the colours for a colour list, and so on.  This class, the
				DocumentComponentClass, is merely for registering the existence of a new
				kind of document component, and providing a mechanism for inserting them
				into new documents.
